drm/vkms: Switch to shmem helpers
Inspired by a patch by Chris Wilson for vgem. Plus this gives us vmap
at the gem bo level, which we need for generic fbdev emulation.
Luckily shmem also tracks ->vaddr, so we just need to adjust the code
all over a bit to make this fit.
Also wire up handle_to_fd, dunno why that was missing.
v2:
- Drop now unused container_of #define (Melissa)
- Make sure we keep creating cached objects, this is for testing
(Thomas)
